Transcripts from spacer sequences within chromosomal repeat clusters [CRISPRs (clusters of regularly interspaced palindromic repeats)] from archaea have been implicated in inhibiting or regulating the propagation of archaeal viruses and plasmids. For the crenarchaeal thermoacidophiles, the chromosomal spacers show a high level of matches ( approximately 30%) with viral or plasmid genomes. Moreover, their distribution along the virus/plasmid genomes, as well as their DNA strand specificity…

Characterisation of the CRISPR/Cas system of the hyperthermophilic Archaeum Thermoproteus tenax
TLDR
The function of the archaeal CRISPR/Cas system is studied in more detail using the hyperthermophilic organism Thermoproteus tenax as an example and sevenCRISPR loci could be identified in the genome of T. tenax.
CRISPR families of the crenarchaeal genus Sulfolobus: bidirectional transcription and dynamic properties
TLDR
Analysis of the partially identical repeat‐clusters of Sulfolobus solfataricus strains P1 and P2 revealed that spacer‐repeat units are added upstream only when a leader and certain cas genes are linked.
CRISPR-mediated defense mechanisms in the hyperthermophilic archaeal genus Sulfolobus
TLDR
Recent progress made in understanding spacer recruitment from foreign DNA, production of small RNAs, in vitro activity of CRISPR-associated protein complexes and attack of viruses and plasmids in in vivo test systems are addressed.
CRISPR-based immune systems of the Sulfolobales: complexity and diversity.
TLDR
Targeting of protospacer regions of invading elements by Cas protein-crRNA (CRISPR RNA) complexes exhibit relatively low sequence stringency, but the integrity of protspacer-associated motifs appears to be important.
Role of free DNA ends and protospacer adjacent motifs for CRISPR DNA uptake in Pyrococcus furiosus
TLDR
It is found that the hyperthermophilic archaeaon, Pyrococcus furiosus, actively incorporates DNA fragments (spacers) from both plasmid (foreign) and host genome (self) sequences into its seven CRISPR loci, indicating that free DNA termini and PAMs are conserved features important forCRISPR spacer uptake in diverse prokaryotes and CRISpr–Cas systems.
CRISPR/Cas system and its role in phage-bacteria interactions.
TLDR
Recent progress made in the CRISPR/Cas system is described, which participates in a constant evolutionary battle between phages and bacteria through addition or deletion of spacers in host cells and mutations or deletion in phage genomes.

Characterisation of proteins involved in CRISPR-mediated antiviral defence in Sulfolobus solfataricus
TLDR
The biochemical characteristics of CRISPR-mediated defense in the crenarchaeon Sulfolobus solfataricus is described, and the recognition and silencing of DNA targets in E. coli has been shown to involve a multiprotein complex termed CASCADE as well as Cas3, a putative helicase-HD nuclease.
Genomic analysis of Acidianus hospitalis W1 a host for studying crenarchaeal virus and plasmid life cycles
TLDR
The small and relatively stable genome of A. hospitalis W1 renders it a promising candidate for developing the first Acidianus genetic systems, and the putative metabolic pathways for sulphur metabolism show some significant differences from those proposed for otherAcidianus and Sulfolobus species.

The Repetitive DNA Elements Called CRISPRs and Their Associated Genes: Evidence of Horizontal Transfer Among Prokaryotes
TLDR
A mechanism by which this HGT has occurred is suggested, namely, that the CRISPR loci can be carried between cells on megaplasmids ≥40 kb in length.
A putative viral defence mechanism in archaeal cells.
TLDR
Analysis of all the current data on archaeal repeat clusters provides some new insights into their diverse structures, transcriptional properties and mode of structural development.
CRISPR Provides Acquired Resistance Against Viruses in Prokaryotes
TLDR
It is found that, after viral challenge, bacteria integrated new spacers derived from phage genomic sequences, and CRISPR provided resistance against phages, and resistance specificity is determined by spacer-phage sequence similarity.
Intervening Sequences of Regularly Spaced Prokaryotic Repeats Derive from Foreign Genetic Elements
TLDR
It is shown that CRISPR spacers derive from preexisting sequences, either chromosomal or within transmissible genetic elements such as bacteriophages and conjugative plasmids, implying a relationship betweenCRISPR and immunity against targeted DNA.
Genomic comparison of archaeal conjugative plasmids from Sulfolobus.
TLDR
Four newly isolated self-transmissable plasmids of the Archaea were sequenced and subjected to a comparative sequence analysis, which revealed three conserved and functionally distinct sections in the genomes.
CRISPR elements in Yersinia pestis acquire new repeats by preferential uptake of bacteriophage DNA, and provide additional tools for evolutionary studies.
TLDR
The authors have sequenced a total of 109 alleles of the three Y. pestis CRISPRs and they describe 29 new spacers, most being specific to one isolate, and it appears that addition of new motifs to a common ancestral element is the most frequent event.
CRISPR--a widespread system that provides acquired resistance against phages in bacteria and archaea.
TLDR
The structure and function of CRISPRs are discussed and the implications of this new antiviral mechanism in bacteria are discussed.
Identification of genes that are associated with DNA repeats in prokaryotes
TLDR
A novel family of repetitive DNA sequences that is present among both domains of the prokaryotes but absent from eukaryotes or viruses is studied, characterized by direct repeats, varying in size from 21 to 37 bp, interspaced by similarly sized non‐repetitive sequences.
Plasmids and viruses of the thermoacidophilic crenarchaeote Sulfolobus
TLDR
Sulfolobus is one of the best-studied archaeons and could develop into an important model organism of the crenarchaea and the archaea and should help to understand the physiology and genetics of the respective genetic elements as well as the host.
